MySQL Insert Where query

Question

What\'s wrong with this query:

INSERT INTO Users( weight, desiredWeight ) VALUES ( 160, 145 ) WHERE id = 1;

It works without the WHE

Answer 1

If you are specifying a particular record no for inserting data its better to use UPDATE statement instead of INSERT statement.

This type of query you have written in the question is like a dummy query.

Your Query is :-

INSERT INTO Users( weight, desiredWeight ) VALUES ( 160, 145 ) WHERE id = 1;

Here , you are specifying the id=1 , so better you use UPDATE statement to update the existing record.It is not recommended to use WHERE clause in case of INSERT.You should use UPDATE .

Now Using Update Query :-

UPDATE Users SET weight=160,desiredWeight=145 WHERE id=1;
